ekotoksisuuden

Ekotoksisuus refers to the harmful effects of chemical substances on ecosystems. It encompasses the toxicity of a substance to living organisms within an environment and the potential for that substance to persist, bioaccumulate, and biomagnify through the food chain. When a substance is ecotoxic, it can disrupt natural processes, harm populations, and alter the structure and function of entire ecosystems.

The study of ecotoxicity involves assessing how different chemicals impact various trophic levels, from microorganisms to plants and animals. Factors such as the concentration of the substance, its duration of exposure, and the sensitivity of the organism are crucial in determining the extent of the harm. Persistent organic pollutants (POPs) are a well-known example of ecotoxic substances that can remain in the environment for long periods and cause widespread damage.

Understanding ecotoxicity is vital for environmental protection and risk assessment. It informs regulations on chemical use and disposal, helping to prevent pollution and safeguard biodiversity. By identifying and evaluating ecotoxic substances, scientists and policymakers can implement measures to mitigate their negative impacts on the natural world and human health.
